The new 5.1.1 update properly displays the percentages as stated. It works well with even the old Growl System Prefs running under OS 10.8. However, when you click the the i button to access the settings, the widget still identifies itself as v5.0.0. Minor issue to a very useful widget if you are a Woot! customer.
At least for me, several attempts at download this application were successful except that I always ended up with Ver. 4.21. When I supposedly “replaced” the existing version, I still got the same version as I had before I downloaded.
Woot! is the best. site. ever. This widget is a great way to keep track of what is going on there. I have two copies in my dashboard, one for woot and one for sellout.woot. Hope to see the shirt and wine option soon.
